1801-1880. American missionary to South Africa. Born in W Pennsylvania and ordained a Presbyterian minister in 1832, he reached South Africa as an American Board missionary in 1835. A mission to the Matabele was abandoned after a Boer attack in 1837, and he joined colleagues among the Zulu in Natal. In 1840-46 he served as minister to the Boers (or Voortrekkers), believing that this would ultimately benefit the Zulu Mission. His devotion won their lasting regard. In 1847 he returned to mission work in the Inanda Location, NW of Durban, where he remained until retirement in 1873. The Inanda Girls' Seminary was opened in 1869. Lindley's attitude to tribal custom mellowed with the years, and he welcomed the ordination of native pastors in 1869, in which respect he proved more liberal than younger colleagues.
